Abstract: A system and a method for operating a lighting device may include a transmission device and an optional communication unit. The transmission device may be configured to wirelessly transmit a radio signal with identification data specific to the transmission device of the lighting device via at least two radio channels. The transmitted radio signal transmitted via a respective one of the at least two channels may include channel data with respect to the respective one of the radio channels. In a non-limiting embodiment, the transmission device is a beacon.

Abstract: Lighting devices with lighting means, transmitting device for transmitting an electromagnetic data signal and energy buffer for current supply of the transmitting device are to be protected from exhaustive discharge. Thereto, an activation device is provided, by which the transmitting device can be activated from an energy-saving mode, in which the transmitting device is switched off, into an operating mode, in which the transmitting device is switched on for operationally transmitting the electromagnetic data signal.

Abstract: A system and a method may be used for operating and/or calibrating a transmitter device. The system and method may include wirelessly transmitting a radio signal with identification data specific to the transmitter device and reference data. The transmitter device may transmit the radio signal with signal properties at least partially dependent on the reference data. A communication device may receive the radio signal and ascertain a distance between the transmitter device and the communication device using reception-side signal properties and the reference data ascertained from the received radio signal. A distance sensor may detect a distance between the transmitter device and the communication device. An evaluation unit may ascertain the reference data depending on the reception-side signal properties of the radio signal and the detected distance and to provide the ascertained reference data in the transmitter device for calibrating the transmitting device.

Abstract: A method for operating a beacon may include repeatedly emitting an identification number. The identification information is encrypted multiple times in a different manner by a one-way function and is emitted during the repeated emission in a differently encrypted form.
